Patent GB-771577-A (GB)
Title: Improvements in and relating to the protection of machine tools
IPC: B23Q15/00
Filed: 1955-01-03
Abstract: 771,577. Machine-tool details. WALDRICH. GES., H. A. Jan. 3, 1955 [Jan. 2, 1954], No. 108/55. Class 83 (3). [Also in Group XXIII] A machine-tool, e.g. a lathe, is provided with a switch 9, which, in the event of an abnormal condition, causes the work and tool to be slightly separated and the headstock or other drive to be stopped. The switch 9 preferably responds to lubricating-oil pressure for the headstock-bearings and forms part of a circuit which includes contactors 1, 2 controlling switches 1 m-n, 2 m-n for low and high-speed rotation, respectively, of a headstock motor 17 of the pole-changing type, and contactors 7, 8 controlling switches 7 m-n, 8 m-n for causing rapid radial advance-and-withdrawal respectively, of the tool-carriage through a motor 18. To start the headstock, a press-button 10 or 11 is closed to energise one or other of the contactors 1, 2 according to the speed of rotation desired. The energized contactor closes contacts 1 e-# or 2 e-# to complete the circuit to the switch 9 which closes contacts 9 a-c when the oil-circulation has been correctly established. The circuit through the latter contacts, energizes an auxiliary-contactor 3 to close contacts 3 e-f to a holding circuit and to open contacts 3 c-d to isolate the contactor 3 from the switch 9. The contactor 3 also completes a holding circuit for the contactor 1 or 2 through the contacts 3 a-b and 1 c-d or 2 c-d, and closes contacts 3 g-h to prepare a circuit through which a delay-relay 6 can be energized if the switch 9, in response to a failure of the oil-pressure, closes the contacts 9 a-b. This movement of the switch also transfers the supply from a green lamp 4 to a red lamp 5 and energizes the contactor 7 which, through the motor 18, retracts the tool-carriage. The relay 6, after the delay to which it has been set, opens contacts 6 a-b to switch-off the motor 17 and de-energizes contactor 3, thus opening the contacts 3 g-h to stop the motor 18. During operation, press-buttons 13, 14 enable the motor 18 to be controlled, while limit switches 15, 16 prevent excessive travel of the tool-carriage. Locking-contacts 1 a-b, 2 a-b, 7 a-b and 8 a-b prevent simultaneous excitation of the contactors 1, 2, or 7, 8.

Title: Improvements in or relating to the processing of crude benzole
Inventor: WEBB WILLIAM HARRY ARLETT
IPC: C07C7/00
Filed: 1958-01-03
Abstract: Aromatic hydrocarbons are recovered from benzole in pure form by first fractionating to obtain a lower boiling benzene fraction and a higher boiling fraction containing toluene and xylenes, then hydrofining each fraction.  In a preferred embodiment forerunnings containing compounds more volatile than benzene are removed, e.g. cyclopentadiene and carbon disulphide.  The benzene fraction should contain not more than 0.1% of toluene and other compounds less volatile than benzene; similar considerations apply to the toluene and xylene fraction.  If desired the forerunnings may also be hydrofined together with the higher boiling fraction. Saturated materials are separated from the hydrofined products by fractionation and the higher boiling fraction may be separated into toluene and xylene.  Specification 892,113 is referred to.

Title: Improvements in apparatus for the determination of the stiffness of gels and a method therefor
Inventor: BURNETT JAMES
IPC: G01N11/16
Filed: 1962-01-04
Abstract: 972,635. Viscometers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 2, 1963 [Jan. 4, 1962], No. 430/62. Heading G1S. The stiffness of a gel is determined by means of a body 9, at least partly immersed therein and rotated in alternate directions by a reversing motor 30 through the intermediary of a coil spring 5. The motor 30 drives a disc 8, through gears 21, carrying a rigid shaft 7 adjustably fixed to the outer part of spring 5. The inner end of spring 5 is fixed to a rotatably mounted shaft 1 carrying body 9 and an arm 25 which engages a contact 26 or 27 when the shaft 1 has been rotated through a desired angle (say 15 degrees) and thus reverses the motor 30. As the stiffness of the gel increases the compression and expansion of the spring 5 increases and thus the angular rotation that must be applied to disc 8 to drive body 9 through the desired angle is increased. Either the gearing 21 or the motor 30 is designed so that as the angle of rotation of disc 8 increases its speed also increases and the rate of rotation of body 9 is maintained. A pointer 14 mounted on a shaft 10 fixed to disc 8 engages a member 16 fixed on a rotatable scale 11 when the disc 8 moves anticlockwise and engages an indicating pointer 15 movable over scale 11, when the disc 8 moves in a clockwise direction. Thus pointer 15 indicates the angular rotation of disc 8 on scale 11, and thus the stiffness of the gel. When the angular rotation of the disc reaches a predetermined value pointer 15 engages contacts 19 to operate an alarm. Recording means may be provided. Specification 842,977 is referred to.

Title: Improvements in or relating to automatic firearms
IPC: F41A9/37
Filed: 1931-01-06
Abstract: 370,900. Automatic guns. WHITE, A. E., 5, Quality Court, Chancery Lane, London.-(Colt's Patent Fire Arms Manufacturing Co. ; Hartford, Connecticut, U.S.A.) Jan. 6, 1931, No. 502. [Class 92 (ii).] Relates to automatic guns of the kind having a longitudinally sliding breech-block 17 carrying a spring-actuated firing-pin 30 which is cocked automatically during recoil by a lever 32 carried by the breech bolt and engaging a recess in the fixed gun casing. According to the invention, a sear 46 carried by the breech block is adapted for horizontal transverse movement for engaging and releasing the firing-pin. The invention is shown applied to a recoil-operated gun of the Colt type as described, for example, in Specifications 133,329, 133,351, and 133,352, [all in Class 92 (ii), Ordnance &c.], and the horizontally-movable sear is shown arranged for operation, synchronously with the rotation of an aircraft propeller, by a trigger-motor M, Fig. 11, capable of being attached at either side of the gun casing. To facilitate the change from one side of the gun to the other certain parts of the sear-mechanism are reversible and the trigger-motor is interchangeable with the guide bracket 40 of a longitudinal rod 42 which serves for hand-operation of the breech-block through a pin 38 thereon, as shown in Fig. 2. The sear shown in Fig. 11 is connected by a bell-crank lever 47 with a vertically movable spring plunger 51 which keeps the sear in engagement with a notch 30c in the firing-pin 30 as shown in Fig. 12. The sear is released when the breech-block is in the forward locked position either by the member m of the triggermotor or by upward pressure on the lever 47 by a trigger-lever 53 operated by a pressbutton 58a arranged on the handle-block, as shown in Fig. 21. The sear and its operating- lever are reversed when the trigger-motor is arranged on the side opposite to that shown in Fig. 11. In a modification the lever 47 is dispensed with, the sear being biased by a horizontal spring plunger and moved horizontally by cam surfaces on a vertical spring- controlled slide. Specifications 365,315 and 365,787 also are referred to.

Patent GB-393684-A (GB)
Title: Improvements in and apparatus for the manufacture and production of metal carbonyls
IPC: C01G1/04
Filed: 1932-01-11
Abstract: <PICT:0393684/III/1> In the production of metal carbonyls by the action of carbon monoxide on carbonyl forming materials in continuous operation by continuously introducing the initial material into and withdrawing the residue from the reaction chamber, the whole of the reaction chamber is at all times kept substantially completely filled with the solid reacting material.  The solid material is preferably at least partly in a coarse form or in the form of granules and additional materials having a loosening effect, such as rings or tubes of aluminium, copper or clay, may be mixed with the reacting material or supplied in alternate sequence therewith. Carbon monoxide under a pressure of 200 atmospheres flows upwards through a reaction chamber h which is wholly filled with small pieces of carbonyl-forming material.  Exhausted material is withdrawn at short intervals through a sluice s by bringing it to the same pressure as the reaction chamber by a pipe l, opening a valve v and setting in motion a worm conveyer t.  When the sluice is filled, the conveyer is stopped, the valve v is closed and the pressure is released, the sluice being emptied through a valve w. Fresh material is introduced similarly by means of a sluice r, valves x, y and a pipe m.  Two sets of sluices may be provided which are operated alternately.  When working with tall containers it is preferable to divide the column of material one or more times by devices which support the material. This may be effected by inserting one or more transverse baffles having for example centrally arranged openings if desired shaped like a funnel, through which the material falls say by the action of stirring arms.  The stirring arms pertaining to each baffle may work with difference efficiencies or be driven at different speeds. Inclined or horizontal reaction chambers may also be employed, the fresh material being introduced under excess pressure so that it completely fills the chamber; additional filling, pressing or promoting devices such as conveyer worms may also be provided at intervals throughout the reaction chamber. Rotating horizontal reaction vessels may be employed, and when working under pressure in such vessels, it may be preferable to rotate one or more tubular insertions having thin walls, the pressure bearing container not being moved.  The withdrawal of the heat of reaction may be effected by internal cooling with cooling tubes or coils, by external cooling ribs, by cooling jackets or by means of gases, such as the reaction gas itself, led through the reaction chamber.  Specification 370,962 is referred to.
